This final note -- two, really, about the oil spill in the Gulf. First, retired Admiral Thad Allen said today the well will finally be killed, once and for all, this weekend. Also, the Interior Department has ordered oil companies to plug as many as 3,500 unused wells on the floor of the Gulf of Mexico. Sounds like a lot, until I tell you there are about 27,000 old wellheads down there.

Oil today, by the way? Down 75 cents to $76 a barrel.
